My moodle site started to act strange all of a sudden, it is slow and crushing now and then, i found that the problem was moodlecron getting processor to work overtime - i disabled it, i had an improvement but now cpu percentage is getting high again and as i understand this time php-cgi.exe is responsible for it.
My php version is 5.4 and i think updating PHP and Moodle version will resolve the issue, what do you guys think? Also cron is mandatory and i can't get it run correctly (runs as a scheduled task)
also sometimes when the slowing down of Moodle occurs i get this to my mail:
Please help me on how to upgrade PHP - which i think it might resolve the issue
